具备纳米级尺寸大小的3D聚酰胺-胺型树枝状高分子(PAMAM),因其表面功能基团丰富、易穿透生物膜、无免疫原性、可生物降解等特点,被广泛用于各种药物分子、基因物质等的输送。PAMAM树状大分子本身具有抗菌、抗病毒能力,能够显著抑制铜绿假单胞菌、金黄色葡萄球菌、单纯疱疹病毒、人类免疫缺陷病毒等的增殖,而以树状大分子为基础的局部抗微生物药也越来越受关注。
3D polyamide-amine dendrimers (PAMAM) with nanometer size are widely used in various fields due to their abundant functional groups, biofilm penetration, non-immunogenicity and biodegradability Delivery of drug molecules, genetic material, etc. PAMAM dendrimer itself has antibacterial and antiviral ability and can significantly inhibit the proliferation of Pseudomonas aeruginosa, Staphylococcus aureus, herpes simplex virus and human immunodeficiency virus, while the dendritic macromolecule-based local resistance Microbiological drugs are also getting more and more attention.
